I'm in same boat... would really love to see a bit more wear to say 3.5, but his right jawbone has enough wear on 3rd premolar to call it 3.5 (interestingly, his left jawbone has almost no wear on 3rd premolar, favoring 2.5).
In other words, if I had only his right jawbone, I'd prob go 3.5.... if I only had his left jawbone, I'd go 2.5
